If you still haven't made your decision I would recommend checking out a Fold-a-Cover. We have been in the business of making Hard, Folding Tonneau covers for over 25 years and we have been supplying our covers to Chrysler for over 18 years as a MOPAR part.
Our G4 Elite cover opens at both the tailgate and the cab. Both panels are independently locked and if your vehicle doesn't have a locking tailgate then the cover will secure your tailgate without the need for an after-market tailgate lock. The cover also utilizes a paddle latch on top of the cover in order to open and gain entry to your truck bed without having to open the tailgate first.
Please head on over to http://www.foldacover.com
to find more information. Or send me a PM if you have any questions.
We are also currently offering an additional $25 off for RamForumz members with the coupon code: RF25FAC
Good luck in your search for a cover!
